Narrow Aisle Lift Trucks
Narrow Aisle Lift Trucks are electric trucks designed to function within narrow aisles. Typical storage aisles are 3.6 meters wide, sufficient space for a counterbalanced lift truck to turn in the aisle. Nonetheless, narrow aisles could be about 2.4 meters wide to as little as 1.8 meters. The narrow space requires specialized types of lift trucks that are small, capable of tight turns, could put away loads without turning. The common types of narrow-aisle trucks are reach trucks, turret trucks and orderpickers.
Narrow-aisle reach trucks
The first kinds of narrow-aisle lift trucks developed for warehouse use are the reach trucks. These small trucks could easily turn in narrow aisles because their design has eliminated the requirement for a large counterweight. Instead, stability is provided by outrigger arms which extend in front of the truck. The downside of this design is that the outrigger arms can hinder access to the storage rack as the truck cannot get close enough. These types of trucks truly work well in a warehouse which is well lit, has clean, even floors, good traffic flow and ample turning space.
Turret trucks
The design of a turret truck has pivoting forks on side of the truck. The forks pivot 90 degrees and move from side to side. The load could face forward whilst the operator drives down the aisle. When it stops at the designated storage place, the truck's forks turn to the storage side and lift the load to their full extension, and next smoothly deposit the load before resuming their original position. Turret trucks are available with a wire guidance system which keeps the truck on its path in very narrow aisles. In man-down trucks, operators remain at floor level.
